that the patient had hereditary coproporphyria. Ten days after her admission she started to develop renal failure with normal urine output. There were no casts or red cells on urine examination. Excretion of so- dium was 39mmol/24h. She underwent plasma exchange and hemodialysis that improved renal function tests but had no effect on jaundice. Fifty days after her admission she developed an un- explained nonproductive cough disturbing her, especially in the supine position, that was not relieved by the usual symptomatic measures. Spirometry was normal. She also developed dystrophic nail changes and alopecia, although she had good nutrition. A liver biopsy performed two months after the first biopsy, showed bile duct proliferation, biliary and fibro- sing piecemeal necrosis and multiple areas with hepato- cellular necrosis. Fibrosis in this biopsy was probably the result of a healing process. The patient showed gradual improvement and was discharged 111 days after her admission, with no jaun- dice or photosensitivity (Figure 4, 5). Forty-five days later she was readmitted to our de- partment with abdominal pain, which, after thorough examination, was attributed to an acute attack of por- phyria. She had no fever, jaundice or photosensitivity. She was given 400gr glucose i.v. daily for a few days with- out improvement. On the contrary, she developed neu- ropathy, which caused tetraparesis and deterioration of the respiratory muscle function although blood gases remained normal. Haem arginate (Normosang) was ad- ministered (3mg/Kg daily for ten days) with gradual im- provement and she was discharged two months after her admission. On February 2001 the patient was last seen in the outpatient clinic and she was able to move her hands and walk with assistance. She had no jaundice or photosensi- tivity.

DISCUSSION Hereditary coproporphyria (HCP) is a very rare dis- order. It is inherited in an autosomal dominant mode but fewer than 30% of patients have an acute attack. Its incidence has been estimated in Denmark to be 2 per million,1 in Czech Republic 1:1700002 and in Japan 1:184000.3 The disease usually presents with symptoms identical to those of acute intermittent porphyria (AIP).

c) stimulation of the vagus nerve in the liver and produc- tion of reflex cough. Another issue is the role of plasmapheresis in the course of our patient’s disease. Bilirubin may be toxic to cell respiration, membrane integrity and transport func- tions.10 Bilirubin and bile salts may cause toxic tubular damage contributing to acute renal failure. A reduction in pulmonary surfactant factor and a toxic effect of bile in hepatocytes has been described.10 Transformation of mononuclear cells is impaired by excess bilirubin, increas- ing susceptibility to infections.11 In view of these obser- vations, the removal of excess bilirubin and bile salts seems justified. Nevertheless there is controversy about the effectiveness of this manipulation, so it is not includ- ed in the standard plasmapheresis indications.12 When hepatic failure is reversible, plasma exchange may be justified, but prognosis depends on the underlying dis- ease.13 In our case this procedure probably did not help in bilirubin reduction, perhaps due to short duration of plasmapheresis. (She had dyspnea and pulmonary ede- ma was suspected, so the procedure was interrupted af- ter two cycles.) On her second admission, we noticed the therapeu- tic effect of the haem preparation on her disease, even after the development of severe neuropathy as it is re- Figures 4, 5.
